Infant mortality in the Saniyo-Hiyowe population, Ambunti District, East Sepik Province

In this small East Sepik population, the infant death rate is extremely high, about 400 per 1000. It has remained at least as high in the generation after contact in the early 1960s as in the generation born prior to first contact with government and missionaries, despite many other kinds of social and economic change. Simple aid post treatment available year round and twice yearly immunization patrols remain a pressing need for small, peripheral populations like this one who are still without these services.
